ReviewGlomerular diseases seen with cancer and chemotherapy: a narrative review.
Glomerular lesions have been recognized in a number of malignant diseases. Membranous nephropathy is the most common glomerular pathology associated with solid tumors. In Hodgkin's disease, the most common lesion is minimal change disease, reflecting possibly an anomaly of T-cell function. ⋯ Failure to recognize certain paraneoplastic glomerular diseases can lead to potentially unnecessary therapies. This review describes the association of glomerular diseases with solid tumors, hematological malignancies, stem cell transplantation, and chemotherapeutic agents. We also describe the pitfalls in diagnosis and the dilemma in treating these entities.

The volatile anesthetic isoflurane induces ecto-5'-nucleotidase (CD73) to protect against renal ischemia and reperfusion injury.
The volatile anesthetic isoflurane protects against renal ischemia and reperfusion injury by releasing renal tubular TGF-β1. As adenosine is a powerful cytoprotective molecule, we tested whether TGF-β1 generated by isoflurane induces renal tubular ecto-5'-nucleotidase (CD73) and adenosine to protect against renal ischemia and reperfusion injury. Isoflurane induced new CD73 synthesis and increased adenosine generation in cultured kidney proximal tubule cells and in mouse kidney. ⋯ The TGF-β1-neutralizing antibody or the CD73 inhibitor attenuated isoflurane-mediated protection against HK-2 cell apoptosis. Thus, isoflurane causes TGF-β1-dependent induction of renal tubular CD73 and adenosine generation to protect against renal ischemia and reperfusion injury. Modulation of this pathway may have important therapeutic implications to reduce morbidity and mortality arising from ischemic acute kidney injury.
